C27H29N5O6S (551.1838)

Bosentan is a dual endothelin receptor antagonist important in the treatment of pulmonary artery hypertension (PAH). It is licensed in the United States, the European Union and other countries by Actelion Pharmaceuticals for the management of PAH under the trade name Tracleer®. Bosentan is used to treat pulmonary hypertension by blocking the action of endothelin molecules that would otherwise promote narrowing of the blood vessels and lead to high blood pressure.

C27H31ClFNO8 (551.1722)

Haloperidol glucuronide is a metabolite of haloperidol. Haloperidol is a typical antipsychotic. It is in the butyrophenone class of antipsychotic medications and has pharmacological effects similar to the phenothiazines. Haloperidol is an older antipsychotic used in the treatment of schizophrenia and acute psychotic states and delirium. (Wikipedia)

4-Hydroxytamoxifen-N-glucuronide

(2R,3R,4R,5S)-3,4,5-trihydroxy-6-{[(2-{4-[(1E)-1-(4-hydroxyphenyl)-2-phenylbut-1-en-1-yl]phenoxy}ethyl)amino]oxy}oxane-2-carboxylic acid

C30H33NO9 (551.2155)

4-Hydroxytamoxifen-N-glucuronide is a metabolite of tamoxifen. Tamoxifen is an antagonist of the estrogen receptor in breast tissue via its active metabolite, hydroxytamoxifen. In other tissues such as the endometrium, it behaves as an agonist, and thus may be characterized as a mixed agonist/antagonist. Tamoxifen is the usual endocrine therapy for hormone receptor-positive breast cancer in pre-menopausal women, and is also a standard in post-menopausal women although aromatase inhibitors are also frequently used in that setting.
